so our xmas lunch which was about 1 hour late. we'd just put most of the things on the table, FIL was the only one sitting down, but he started filling his plate. then started eating it, whilst everyone else was getting little ones organised, making sure we had everything we needed at the table etc.
AIBU to think he should have waited and think this is rude and he no manners??
he was pretty gutted though when we remembered the mint sauce and he'd already finished his lamb
he does this all the time and i think its just the rudest thing.
